1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The purpose of this study was to determine the relationship between the serum levels of kappa (κ) and lambda (λ) total light chain (TLC), the κ/λ ratio, and the combined serum TLCκ and TLCλ (ΣTLC) levels in Chinese centenarians and all-cause mortality. The association between serum TLC and all-cause mortality was investigated using restricted cubic spline (RCS) analysis, Cox proportional hazards models, and Kaplan‒Meier curves. The study included 906 centenarians (18.8% male), 838 (92.5%) of whom died during a median follow-up of 30 months. The proportions of centenarians with abnormal TLCκ and TLCλ levels were 68.1% and 49.0%, respectively. RCS analysis indicated that the levels of TLCκ, TLCλ, and ΣTLC were associated with all-cause mortality (P < 0.05), whereas the κ/λ ratio was not (P > 0.05). Cox proportional hazards analysis demonstrated that the highest quartiles of TLCκ, TLCλ, and ΣTLC were associated with an increased risk of death, with hazard ratios of 1.434 (95% confidence interval [CI], 1.061-1.939; P = 0.019), 1.351 (95% CI, 1.013-1.802; P = 0.041), and 1.891 (95% CI, 1.347-2.654; P < 0.001), respectively. Kaplan-Meier analysis illustrated that centenarians with higher levels of TLCκ, TLCλ, and ΣTLC had significantly shorter median survival times (26 months versus 35 months, P < 0.001; 26 months versus 32 months, P = 0.003; and 26 months versus 36 months, P < 0.001, respectively). Our findings suggest that serum levels of TLCκ, TLCλ, and ΣTLC are significantly associated with all-cause mortality in centenarians. Trial registration Not applicable.
